/* ** ** Swift/XRT hardness ratio for M87. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 57845.914122 0.002586 0.11089 0.02696 0.70225 1 1.15653 0.08927 0.56003 0.04322 0.12825 0.02957 0.06212 0.01432 57845.918349 0.001641 0.20389 0.05129 0.67257 1 1.04784 0.11287 0.50874 0.05479 0.21365 0.04856 0.10360 0.02355 57845.921762 0.001743 0.18666 0.04643 0.65000 1 1.12388 0.10935 0.53698 0.05224 0.20978 0.04803 0.10025 0.02295 57846.045567 0.122061 0.17137 0.04317 0.01161 1 1.47808 0.15486 0.47210 0.04945 0.25329 0.05803 0.08008 0.01835 57846.170257 0.002600 0.16222 0.03786 0.64246 1 1.53708 0.14820 0.48297 0.04657 0.24934 0.05300 0.07852 0.01669
